Scroll

Scroll is a native zkEVM Layer 2 for Ethereum, built by Scroll Foundation, that uses zero-knowledge proofs to scale Ethereum while preserving bytecode equivalence with the EVM. Developer surface is dominated by standard Ethereum JSON-RPC endpoints on mainnet and Sepolia testnet, the Scrollscan block explorer (with an Etherscan-compatible REST API), a canonical L1<>L2 bridge with messenger contracts, and a rollup explorer that surfaces batch and proof status. dApp builders use Scroll as a drop-in EVM target with Hardhat, Foundry, viem, ethers, and other standard EVM tooling.

Scroll publishes 9 API contracts indexed on the APIs.io network, including JSON-RPC API, and 8 more. Tagged areas include zkEVM, Layer 2, Ethereum, Rollup, and Zero Knowledge.

The Scroll catalog on APIs.io includes 1 Spectral governance ruleset.

Scroll’s developer surface includes documentation, GitHub presence, engineering blog, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
